I ask the foundry to cast nickel alloys and I took a piece metal to do a chemical test.
The element composition of the nickel alloy is Ni 70% Cr 12% Fe 1.2% Mo 2.5%...so far they all are in the allowable range.
But I found the alloy also contains W 0.004% !
Is this the normal condition ? ?
I check the regulation of chemical composition , it only indicates that this alloy need contain Ni ..% Cr ..% Fe..%...but it doesn't say the limit of other impurity of element.
And may SS 316 contain a little bit other impurity element like W 0.03%, V 0.02% ?? Normal??
